Description |
Isobornylacetat er en slags acetatester. Den kan produseres gjennom forestringen mellom acetat og kamfen. Det er et slags smaksstoff med duft, og kan brukes som mellomprodukt som trengs for å produsere medisinsk syntetisk kamfer. |

|
Description |
Isobornyl acetate has a pleasant, camphor-like odor reminiscent of some varieties of pine needles and hemlock, and a fresh, burning taste. May be prepared by treatment of camphene with acetic acid, usually in the presence of a catalyst; also by acetylation of isobomeol; depending on the starting material (d-camphene or ι-camphene), the resulting acetate may exhibit a slight optical activity; the commercial product is considered to be optically inactive. |
|
Kjemiske egenskaper |
Isobornylacetat har en behagelig, kamferaktig lukt som minner om noen varianter av pinjenåler og hemlock og en frisk, brennende smak |
|
Kjemiske egenskaper |
Fargeløs væske; lukt av furunål. Løselig i de fleste faste oljer og mineraloljer; uoppløselig inglyserol og vann. Brennbar. |
|
Kjemiske egenskaper |
Isobornyl Acetate
has been identified in a number of essential oils. It is a colorless liquid
with a pleasant, pine-needle odor. Isobornyl acetate is prepared from
camphene and acetic acid in the presence of acidic catalysts (e.g., sulfuric
acid) or on a styrene–divinylbenzene acid ion-exchanger. |
|
Uses |
Sammensatt lukt av furu-nål, toalettvann, preparater for badekar, antiseptiske midler, teaterspray, såper, noe som gjør syntetisk kamfer, smaksstoff. |
